Yamaha EM1620 - Manual (Page 6)

® LIMITER indicator
EMI620 is equipped with a limiter circuit which can
limit the maximum level of signal at the SP OUT to
prevent the signal from distorting.
The LIMITER indicator is lit when the limiter cirT
cuit is activated.
© PROTECTION indicator
The PROTECTION indicator lights for approxi­
mately 6 seconds after the POWER switch is pressed
to indicate that the protection circuitry is operating.
No sound is output at the SP OUT while this indica­
tor is lit. This indicator will also light and the sound
will be cut off at the SP OUT when the protection
circuitry is activated at any other time during the
amplifier operation due to factors such as a detec­
tion of excessive DC voltage at the SP OUT or a
thermal overload. When the problem is corrected,
the protection circuitry is automatically deactivated,
the indicator goes out, and the amplifier resumes
normal operation.

© LINE and MIC INPUT connectors
Each input channel offers a choice of two input
connectors: a MIC IN connector, a balanced 4 kohm
impedance XLR-3-31 connector; and a LINE IN
connector, an unbalanced 10 kohm impedance 1/4"
phone jack. The MIC connectors are primarily in­
tended for use with professional low-impedance
microphones or electronic instruments having low-
impedance balanced outputs. The LINE connectors
will accept unbalanced signals from musical instru­
ments or other such source equipment.
© PHANTOM MASTER switch
This switch applies built-in standard +48 V power
to all MIC (XLR) input connectors for biasing Phan­
tom powered condenser microphones.
MICROPHONE CABLES AND MICROPHONES
CONNECTION
TO PREVENT HAZARD OR DAMAGE, ENSURE
THAT ONLY MICROPHONE CABLES. AND
MICROPHONES DESIGNED TO THE IEC268-
15A STANDARD ARE CONNECTED.
© SP OUT 1 and 2 jacks
SP OUT I and SP OUT 2 are standard mono 1/4"
phone jacks. The jacks are wired in parallel and, as a
result, if you connect a speaker system to only one
of the two jacks, then the total load impedance of
the speaker system may be no less than 4 ohms. If
you plug speaker systems into both of the SP OUT
jacks, the total load impedance of each speaker sys­
tem must be no less than 8 ohms.
